and which consequently,-require to be very strongly and solidly constructed, in order to support the heavy loads and withstand the rough usage to which they are subjected.

Heretoiore, reels for the described, and other similar purposes, have been constructed so far as I am aware, either wholly of wood, or partly of wood and artly of cast iron. Such reels are necessari and consequently clumsy, satisfactory in practice.

The object of my invention is to improve the construction of reels of the class described b making the heads, which are necessarily 0 large diameter and must be capable of supand do not prove porting a great weight, out of sheet-metal,-

which is pressed into shape to admit of readyand secure attachment of the hub to the.

heads, and to impart great rigidity and stiffness to the latter as well as to the whole structure. The heads are also rovided with means whereby the reel may e mounted on bearings, so that it can be rotated, as for instance, while the wire or cable is being wound onto, or unwound from the reel.

The construction of my improved reel will now beidescribed in detail," reference being had to the accompanying drawings, in which,

Figure 1 is an end elevation of a reel-cinbodying In invention; Fig. 2 is a central longitudina section thereof; Fig. 3 is an end View of a modified construction, and Fig. 4' is acentral longitudinal section thereof.

My im roved reel consists primarily in a hollow cy indrical hub 1,made of sheet metal,

' pzeferably steel, the same beingformed by nding a plate of suitable size into cylindrical form, the longitudinal seam between e same being preferably secured by a butt-riveted joint, shown in Fig. 2, the same-comprising a longitudinal strip 2, secured to both ed ace of the seam by rivets 4. The joint may be Welded, if preferred.

The other com onent. parts of my improved reel are t e heads 5,, 5, which are y very heavy made from steel-plates pressed into the desired shape in dies the axial sleeve or tube 6, i which is secured at its ends to the heads and which forms the journal by which the reel may be pivotally mounted, and the bolts 7 which secure the component parts of the structure together.

steel-plate, a disk of the desired diameter being first cut out and then placed in dies in which it is pressed, in the usual way, into the shape shown. \Vhen completed, it has a con- 5 tral circular boss 8, in the center of which is i formed a circular aperture for the reception of the end of the sleeve 6, the edge of said aperture being preferably oli's'et, as shown at 9. The walls of said central bosses are curved cated at 1(). Circularly arranged projections or shoulders 12, of larger diameter than the bosses 8, are formed on the opposite sides of j the disks from said bosses, said shoulders or projections serving to internally support the ends of the hubs in the completed reel. The edges or )eripheries of the disks may be left flat, but i prefer to turn the same over 1 to form aflange 13, which serves to strengthen i the reel as well as to'form a bearing surface for the same when it is not pivotally supported.

At the same time as the disks are pressed into the shape just described a number of radial ribs 14 are, or may be, formed therein, the function of which is to im art greater rigidity and stiffness to the-head? l Near each end of the sleeve 6 is formed a shoulder 16 against which the inner edges of the central apertures in the heads bear, and I the ends of the sleeve can then be riveted 1 over to permanently and securely attach said I sleeve to the heads, as shown in Fig. 2. i In order to secure the hub tween the heads, .on the'shoulders 0r projections 12 of which the ends of said hub rest, j the bolts Tare passed through suitable holes 5 formed in the heads Within the said circular project-ions or shoulders, when the nuts 17 on said bolts are tightened the whole structure l is rigidly secured together. i The modification in the structure of my 5 improved reel, shown in Figs. 3 and 4, re-

sides in this, that, instead of the continuous circular shoulder or projection 12, a number of separate projections or shoulders 18 are formed by punching the metal of the head inwardly at a number of equidistant points- The heads are made, as I have stated, of

E around into theplane of the disk, as indi i 1 in place bein e-eireleioisiie desired diameter. "The 430 persons familiar with the ertof metaL working from an inspection oi the drawing.

In thisform of my invention I liave shown an additional sleeve 19 suriounding the oentrel sleeve or. journal 6, the ends of said sleeve 19 hearing against the inner surfaces of the offset portions 9 of said heads-surrounding the central apertures; This sleeve 19 takes the place of the shoulders 16 of the than the latter.,tl1e ends of said liub fitting l sleeve 6,-descrilved in the form ofmy invention shown 1n Figs. 1 and reel is the same.

in assembling the parts, the hub 1 is placed 1 v over the sleeve 6, or sleeves 6 and 19, and t me heads 5 are slipped over the ends of sleeve t3,-

with their shoulders or project-ions fitting within the ends of the hub, the bolls are then put in place and finally the ends of thesleeve 6 are flanged or riveted over.

Having thus describedguy"invention and Without wishing to lie'liinited to the exactform and details of construction shown, what 1 claim is 1. A. reel of the class consisting of a hollow, cylindrical SilOBlmetal hub, pressed steel heads each having a" series of circularly arranged integral shoulders or projections fitting within the ends of said hub to support the same concentrically, said heads also having central cireular'nperlines, a tubular journal passed through said in other re spects the construction ot the two forms of described, the same sense?
